A short history of Xi'an (Chang'an)

Long before any emperor, people were already living well here. Around 6,000 years ago, a farming village of the Yangshao culture (仰韶, Yǎngsháo) stood at Banpo (半坡, Bànpō), on the eastern edge of modern Xi'an. Its people grew millet, kept pigs, hunted with bows, and fired painted pottery — red bowls brushed with fish and human-face designs that are now icons of Chinese prehistory. The village was ringed by a defensive ditch, and its layout is often read as a matrilineal community. Banpo is the quiet reminder that Xi'an's story doesn't start with the First Emperor — it starts with farmers who picked the right plain.

The first great dynasty to rule from this plain was the Zhou (周, Zhōu, c. 1046–256 BC). Their twin capital Fenghao (丰镐, Fēnghào) stood on the Fen River just west of today's city, and from it the early Zhou kings ran a ritual state whose bronze vessels still anchor Chinese museum collections. Geography explains the choice. The Guanzhong plain (关中, Guānzhōng) — the Wei River valley walled in by mountains and threaded with a handful of passes — was fertile, defensible, and close to the western frontier. Every later dynasty that made Xi'an its capital was buying the same real estate.

The Qin (秦, Qín) were a frontier state on the plain's western edge, tougher and more ruthless than their rivals. In 221 BC their king, Ying Zheng (嬴政, Yíng Zhèng), finished conquering the last of them and declared himself Qin Shi Huang (秦始皇, Qín Shǐhuáng) — First Emperor. In barely a decade of rule he standardized the script, the currency, weights and measures, even the axle widths of carts, and rammed straight imperial highways out from his capital at Xianyang (咸阳, Xiányáng), across the river from modern Xi'an. He also conscripted hundreds of thousands of laborers to build his tomb and its terracotta army. The dynasty collapsed three years after his death in 210 BC. The template he hammered together — one China, one script, one administration — lasted two thousand years. From this plain, the idea of one China was forged — which is why Xi'an, not Beijing or Nanjing, is called the root of the nation.

The Han (汉, Hàn, 202 BC–220 AD) built a new capital just southeast of today's center and named it Chang'an (长安, Cháng'ān) — "Perpetual Peace." It grew into one of the largest cities on the planet, and under Emperor Wu (汉武帝, Hàn Wǔdì) it became the launch point of the most famous trade network in history. In 138 BC the emperor sent an envoy named Zhang Qian (张骞, Zhāng Qiān) west to find allies against the nomadic Xiongnu (匈奴, Xiōngnú). He came back thirteen years later with no alliance but a full report on Central Asia — and the missions, garrisons and caravans that followed became the Silk Road. Silk went west; horses, grapes, glass and eventually Buddhism came east, through Chang'an's gates.

After centuries of division, the Sui (隋, Suí) reunified China and in 582 laid out a colossal planned capital on the plain — a perfect grid of walled wards. The Tang (唐, Táng, 618–907) inherited it, restored the name Chang'an, and presided over its golden age. At its peak, around a million people lived inside a wall circuit of roughly 36 km — almost certainly the largest city in the world, and surely the most cosmopolitan. Sogdian merchants ran the West Market, where Persian silver circulated; Turkic princes, Japanese monks and Korean students crowded the wards; Zoroastrian, Nestorian Christian and Manichaean temples operated alongside Buddhist monasteries. The monk Xuanzang (玄奘, Xuánzàng) returned from India with hundreds of sutras, and the Big Wild Goose Pagoda was built to house them. The imperial family kept a hot-spring retreat at Huaqing Palace, stage of China's most retold imperial romance — Emperor Xuanzong and Yang Guifei (杨贵妃, Yáng Guìfēi).

The end was ugly. The An Lushan rebellion (755–763) wrecked Tang power, and in the dynasty's final decades Chang'an was sacked more than once. When the Tang fell in 907, the capital moved east — and never came back. Xi'an spent the next thousand years as a big regional city rather than the center of the world. Its most visible monument dates from that long twilight: the city wall you see today was built by the Ming (明, Míng) in the 1370s, enclosing a much smaller city around the Bell Tower. The Ming also gave it its current name — Xi'an, "Western Peace." Then, in 1974, drought-stricken farmers digging a well in Lintong (临潼, Líntóng) hit a terracotta head, and modern Xi'an found its second life as the place where the world comes to meet ancient China.
